Ingredients
  

For the cake:

  • 1 cup 230g unsalted butter
  • 200 g dark chocolate chopped or chips
  • 1 cup 200g white sugar
  • ½ cup 100g brown sugar
  • ¾ cup 75g unsweetened cocoa powder
  • 1 teaspoon vanilla extract
  • 4 large eggs
  • 1 cup 125g all-purpose flour
  • ½ teaspoon salt
  • 1 teaspoon baking powder
  • Optional for extra fudginess:
  • ½ cup sour cream or plain yogurt
  • ½ cup strong brewed coffee

For the ganache topping (optional):

  • 200 g dark chocolate
  • ½ cup 120ml heavy cream
  • 1 teaspoon butter

Instructions
 

  • Melt the butter and chocolate together in a heatproof bowl or pot until smooth, then let it cool slightly.
  • Whisk in both sugars and the cocoa powder until the mixture is smooth and dark.
  • Add the eggs one at a time, whisking well after each, then stir in vanilla, sour cream, and coffee if using.
  • In a separate bowl, mix the flour, baking powder, and salt, then fold into the wet ingredients until just combined.
  • Pour the thick batter into a greased or lined 9-inch cake pan, smooth the top, and bake at 175°C (350°F) for 30–35 minutes. The edges should be set, and the center still slightly soft.
  • Let the cake cool in the pan for 10 minutes, then transfer to a rack to cool completely.
  • Ganache topping:
  • Heat the cream until it begins to simmer, then pour over chopped chocolate. Wait 1 minute, stir until smooth, add butter for shine, and pour over the cooled cake. Let it set before slicing.

Notes

  • Use high-quality dark chocolate (at least 60% cocoa) for best results
  • Don’t overbake to keep the center gooey and fudgy
  • Chill the cake before slicing for cleaner edges and denser texture
